The measures of x and u are the same, x degrees. the measure of angle s is twice the measure of angle y

Icould really use some with this question.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29

Which best describes the function on the graph? direct variation; k = −2 direct variation; k = -1/2 inverse variation; k = −2 inverse variation; k = -1/2
